The drawing shows the type of truck in common use for hauling industrialplants. It ternal combustion engine and stacking materials in undercontrol of an operator. The operator control station includes aforwardly facing seat pan l on top of the truck 2 together with thenecessary controls including the steering wheel 3. Pivoted to the irontof the truck 2 ahead of the ,operator and on a horizontal transverselyextending axis is a swingable upright lift tower assembly 4 whichincludes the vertically adjustable elevator 5. ln use the elevator' 5can be adjusted to various vertical positions under control of the mentci the tower can he' inclined downwardly or upwardly to-facilitatepicking up the load and its transportation. AUsually the load will beplaced on a raised platform or container and in position of the-elevatorfor stacking According to the present invention a safety the operatorsstation to may be driven by an in-v operator andv by the tiltingadjustsupporting -on the able thereon, an upright supportv mounted on2s, me', s No. senese (or. ere-11e) upper ends oi the guide rails ci theswing` tower bly d. Supplementing the bars are a pair of side rails i2each having its forward end tted to the adjacent end of the axle i@ withits rearward end t inwardly and welded or otherwise secured to theneighboring bar E adjacent the supporting shaft l?. To complete thetransversely extending By rewn of the construction' described the guardassembly bridges the operator's station and by reason of its pivotalconnection with the tower assembly and its pivotal support on therearward hinged uprights ing movement of the tower so as to aiiordcomplete protection to the operator in all relative positions of theparts. Thev structure described is free of complica-ted mechanisms andcan be easily built up fromreadily available parts without specialequipment. While only one embodiment has been described it is to beunderstood that the invention is capable oi various modifications suchas come within the scope of the appended claims.
